The Goodman 20162903 Primary Limit Switch is a genuine OEM safety control designed for VMSS960603BNAA gas furnaces and compatible Goodman/Amana equipment. This normally-closed high-limit switch monitors heat-exchanger and plenum temperature, opening the gas-valve circuit at its 150°F trip point to protect against overheating from restricted airflow, a dirty filter, or blower failure. A failed or nuisance-tripping limit switch is one of the most common causes of a furnace that short-cycles, drops out on heat, or throws a limit-fault code.

Part number: 20162903
Function: Primary high-limit / thermal cutout
Trip point: 150°F (auto-reset)
Configuration: Normally closed (opens on temperature rise)
Fits: Goodman VMSS960603BNAA and compatible models
Brand: Goodman OEM

OEM vs. Generic: This genuine Goodman part is calibrated to the exact factory trip temperature and terminal geometry, so it drops in without adapters and preserves your equipment's safety certification. Generic universal limits can vary in cutout tolerance and mounting, risking nuisance trips or improper protection. For a safety-critical control, OEM is the recommended choice.

Installation difficulty: Easy (1/5). Power down the furnace at the disconnect, remove the two mounting screws, transfer the spade connectors, and reinstall — typically a 10-minute repair for a homeowner comfortable working inside the burner compartment. Always verify with the wiring diagram on the blower-door label.
